Definition
Occupational therapists provide treatment for people recovering from a mental or physical illness to regain their independence and stability and to engage in normal daily occupations (work, home, family life, school, leisure). Occupational therapists provide particular emphasis on interventions that result in improved quality of life and decrease hospitalization.

The code goes in the taxonomy field of the NPI application in NPPES, and on claims where a payer asks for it — box 24J (shaded) or 33b on the CMS-1500 with the ZZ qualifier, or the PRV segment of an 837 electronic claim. Payers match it against the taxonomy on the NPI record and, for Medicare, against the specialty on the enrollment, so all three should agree. To see which code a provider uses, search their NPI in the lookup.
